This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111.5).Atmospheric airsheds, surface areas that contribute contaminants and/or pollutants to a defined location or the airmass above this location, have been previously defined as spatially and temporally static. Dr.s Julie Snow and Jack Livingston at Slippery Rock University of Pennsylvania and Dr. Peter Weiss-Penzias at the University of California, Santa Cruz will address the need for more meaningful airshed delineations by exploring the variability of airsheds. Further, the research will examine how temporal and spatial changes in airsheds relate to air quality and mercury deposition variability and evaluate environmental factors that significantly affect changes in air quality chemistry and mercury deposition rates. The project will incorporate three objectives: (1) Delineate atmospheric contribution basins (airsheds) based on long-term back trajectory trends, which will allow for the analysis of spatial and temporal variability of these basins. (2) Determine the relationship between airshed geometry and air quality (including specific considerations of criteria pollutants and mercury deposition). This portion of the research will integrate air chemistry data that is publicly available from the EPA and mercury deposition data that is publicly available from the Mercury Deposition Network (MDN) with airsheds in Pennsylvania. (3) Create a website to host a user-friendly airshed delineation extension for the ArcGIS platform that integrates with the National Oceanic and Atmospheric Administration HYSPLIT trajectory model for use as a research and teaching tool. The available extension will allow the user to delineate contribution basins based on the frequency of back trajectory paths for a given time period and location.The development of tools for defining airsheds and their variability, quantifying inputs of pollution to the airsheds, and understanding regional air transport will integrate existing approaches and technologies in a novel way. In doing so, the project will reconsider the temporal and spatial variability in regional air transport and improve our understanding of air quality and mercury deposition variability in Pennsylvania. While this work is critical to directing air quality policy, it is equally important in developing accurate air quality forecasts, which will improve the health of individuals and communities. The final result of the project, an ArcGIS extension made publicly available via a webpage, will provide a unique tool for examining regional air quality and teaching undergraduate students; the tool will enable individuals to explore regional atmospheric transport for any given location. Undergraduate students at Slippery Rock University will participate in the development of the webpage, the authoring of documentation, and troubleshooting end user concerns. The dissemination of results will occur broadly through peer reviewed publications and presentations.

该奖项是根据2009年《美国复苏和再投资法案》(公法111.5)资助的。大气气房，即对特定地点或该地点上方的气团造成污染物和/或污染物的表面积，以前被定义为在空间和时间上是静态的。宾夕法尼亚Sippery Rock大学的Julie Snow博士和Jack Livingston博士以及加州大学圣克鲁斯分校的Peter Weiss-Penzias博士将通过探索风口的可变性来解决对更有意义的风口划定的需求。此外，这项研究还将研究空气室的时间和空间变化与空气质量和汞沉积变异性之间的关系，并评估显著影响空气质量化学变化和汞沉积速率变化的环境因素。该项目将包括三个目标：(1)根据长期回溯轨迹趋势划定大气贡献盆地(空气棚)，从而能够分析这些盆地的空间和时间变异性。(2)确定风口几何形状和空气质量之间的关系(包括对标准污染物和汞沉积的具体考虑)。研究的这一部分将把EPA公开获得的空气化学数据和汞沉积网络(MDN)公开获得的汞沉积数据与宾夕法尼亚州的通风棚结合起来。(3)建立一个网站，将ArcGIS平台与美国国家海洋和大气管理局HYSPLIT轨迹模型整合在一起，作为研究和教学工具，为ArcGIS平台提供一个用户友好的机场划定扩展模块。可用的扩展将允许用户根据给定时间段和位置的回程路径的频率来描绘贡献盆地。开发工具来定义风洞及其可变性，量化对风洞的污染输入，以及了解区域航空运输，将以一种新的方式整合现有的方法和技术。通过这样做，该项目将重新考虑区域航空运输的时间和空间变异性，并提高我们对宾夕法尼亚州空气质量和汞沉积变异性的理解。虽然这项工作对指导空气质量政策至关重要，但在制定准确的空气质量预报方面也同样重要，这将改善个人和社区的健康。该项目的最终结果是通过网页公开提供的ArcGIS扩展，它将为检查区域空气质量和教授本科生提供一个独特的工具；该工具将使个人能够探索任何给定地点的区域大气传输。Slippery Rock大学的本科生将参与网页的开发、文档的编写和最终用户的故障排除。将通过同行评议的出版物和专题介绍广泛传播成果。
